horizontal coordinate system  

Définition(s)

  • The horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane to define two angles: altitude and azimuth. Therefore, the horizontal coordinate system is sometimes called as the az/el system, the alt/az system, or the alt-azimuth system, among others. In an altazimuth mount of a telescope, the instrument's two axes follow altitude and azimuth. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Horizontal_coordinate_system)
